The invention discloses a double-motor single-electric drive axle assembly which comprises a main drive motor and an auxiliary drive motor and further comprises a main speed reducer, an auxiliary speed reducer, a planetary gear speed reducer, a differential mechanism, a first half shaft and a second half shaft. An output shaft of the main driving motor is connected with the input end of the main speed reducer, an output shaft of the auxiliary driving motor is connected with the input end of the auxiliary speed reducer, and the input end of the planetary gear speed reducer is in dynamic coupling connection with the output end of the main speed reducer and the output end of the auxiliary speed reducer at the same time. The output end of the planetary gear reducer is connected with the input end of the differential mechanism, and the output end of the differential mechanism is connected with the first half shaft and the second half shaft. According to the double-motor single-electric drive axle assembly, the size can be reduced as much as possible on the basis that the motor power and the output torque are improved, and occupied chassis space is reduced. The invention further discloses a vehicle which has the beneficial effects mentioned above.
